Arthur may have been a short-lived storm, but its impacts certainly weren't. The storm's remnants remained a threat for days after its degradation, bringing significant flooding to the Southeast.

Genesis

Arthur's beginning was an interesting one. Forming off of the old moisture of Tropical Storm Cristina, an area of showers and storms moved around the northern end of a Central American Gyre that was holed up in the region.

This area of showers and storms began to look more organized as it formed into a broad area of low pressure in the Bay of Campeche on June 12.

This area of low to the north and moved into Mexico on June 14 and was expected to move back out into the Gulf.

The low was designated AL90 early on June 16 and was eventually named Potential Tropical Cyclone One the same day.

It emerged out over the Gulf and intensified to Tropical Storm Arthur on June 17. It soon moved back into Texas the same day and weakened to a remnant low late June 17. But the threat was not just on the 17th.

Even though Arthur fell apart late June 17, its effects lasted for days.

Storm recap

Tropical Storm Arthur was a sloppy, short-lived system near the Texas Coast in mid-June, but its legacy was in its heavy rain across the South.

Lets take each day's highlights.

Early morning on June 17, just over 8.5 inches of rain fell in Freeport, about 50 miles south of downtown Houston, where at least one vehicle was flooded.

Two to three-inch rain totals were also reported on the south and east sides of the Houston metro from Baytown to Seabrook and League City.

June 18: The day of flash flood emergencies

Several flash flood emergencies, the highest level flood alert issued by the National Weather Service, were issued June 18 as what is left of Arthur continues to churn moisture into the region.

A separate flash flood emergency was issued for central and southern Avoyelles Parish. Emergency management reported thunderstorms over the parish. Between 12 and 26 inches of rain fell.

Another flash flood emergency was issued for Stone County, Mississippi. Rainfall between 6 and 10 inches, with isolated totals exceeding 10 inches.

Flash flood emergencies were issued Thursday morning in Nicholson and Picayune, Mississippi, where flooding on Hobolochitto Creek was forecast to be the highest in at least 29 years. Multiple homes were flooded and streets closed in Picayune, with over a foot of water, according to a storm chaser.

A flash flood emergency was then issued Thursday afternoon for central Pearl River County for the Anchor Lake Dam on the East Hobolochitto Creek.

Another flash flood emergency was issued for southern Avoyelles Parish, Louisiana, where multiple roads were reported flooded in Simmesport. Up to 2 feet of rain has fallen between June 17 and the morning of June 18.

Finally, another emergency was in effect for Stone County, Mississippi, where water rescues are ongoing following 6-10 inches of rain.

Other flooding and tornadoes

Elsewhere, 1 to 2 feet of flooding was reported in Slidell, Louisiana, and flooding was also reported in Brooklyn and Wiggins, Mississippi.

Earlier June 18, power flashes from an apparent tornado were seen in the western and northern New Orleans metro area with a distinct radar hook echo. Damage to buildings, trees and power lines was reported in Metairie and a 67 mph gust was clocked at Lakefront Airport.

That tornado apparently continued over Lake Pontchartrain into areas near Slidell, Louisiana.

There were two tornado reports in Coffee and Dale Counties, Alabama, on June 17. Stone County, Mississippi, saw a tornado report on June 18.

Flooding was reported in a home in St. Rose, Louisiana, west of New Orleans, and was reportedly widespread in the northern parts of the New Orleans metro, according to a storm chaser.

The rainfall from Arthur largely wrapped up by June 19, but some remant rainfall led to more flooding due to the soils already being so saturated.

Rainfall Totals

Several records were broken or potentially broken by the rainfall associated with Arthur.

In New Orleans, a nearly 70-year record was blown away. The city received 7.75 inches in one day on June 18, breaking the old daily record of 1.74 inches in 1957 for the day.

The graphic below shows the rainfall totals from Tuesday, June 16, when the system began dropping rain along the Texas Coast to early Friday morning, June 19 when the remnants of Arthur began to move off the Southeast coast.

The bulk of this rain fell on Thursday, June 17-18 as the system made its way across Gulf Coast and Southeast with some locations picking up more than 20 inches of rain.

But two records have yet to be verified – the state record for rainfall in one day and the state rainfall record for tropical cyclones.

Over 22 inches fell in Plaucheville, Louisiana, in one day, and over 35 inches may have fallen on Cottonport, Louisiana, which could set the state rainfall record for tropical cyclones.

Both records will need to be verified later this year.
